Nanosuits, powerful prosthetics, and brain-computer interfacing seemed far-fetched when the original movie hit theaters. Now, with a remake nearly three decades later, the plot is closer to reality than you may think.

The K5 robot, developed by Sunnyvale, Calif.-based Knightscope, is designed to be a surveillance robot for law enforcement, private security firms, schools, and anything else looking for an extra set of eyes and ears on the ground. The 5-foot, 300-pound robot can roam autonomously, sending back real-time data about an area with technology that does facial recognition, lidar mapping, and 360-degree video. CNET's Kara Tsuboi got a closer look at what makes the K5 robot tick.
